IMPROVEMENT m PRINTING SILKS AND OTHER-TEXTILE FABRlCS' arm Schedule referred a am Letters Patent and maldng part of ms "no.

To all whom it may concern.-

' Be it known that LLOUIS PRANG, of Boston, in the county of Suffolk and State of Massachusetts, have,

invented a new and useful" Improvementin Preparing Silk and other Textile Fabrics for Printing; and I do. hereby declare that the following is a full, clear,

and exact description thereof, which vill enable others skilled in the art to make and use the same. My invention has for its object to facilitate the proper printing-of silks, laces, and other textile fabrics of a pliable character in one or more colors; and

My invention --consists in temporarily backing or mounting the fabric to be printed with paper or other suitable stifi' material, in sucha manner as to impart to the fabric the necessary firmness, so that it may be made to register properly during the printing operation, as hereinafter more fully described.

In preparing the fabric for printingltakepaper or other suitable material having the necessary firmness and thickness, and cover it with a light coating of paste or other suitable adhesive. material, and allow it to dry, When about to be used the backing thus prepared is dam ened, and the fabric which is tohe printed is sprea smoothly upon the backing.

The printing of one or more colors is then done in the ordinary manner the temporary stifl'ness afl'orded by the backingpermits' the accomplishment of a perfeet register on the press.

When the printed-color or colors have become dry, the mounted and printed fabric is placed between damp sheets of paper or other damp material until the adhesive material of the backing has become so softened, as to permit the printedfabrie to be easily're' moved from the backing. Any other suitable method of dampening the backing may be employed,

; 'This invention facilitates the printing in proper register of various colors "the mostdelicate and pliable fabrics. v

. The improvement is therefore especially adapted to the printing of chromatic pictures and designs upon pliable fabrics of all kinds-f f A-great 'diiiicul'tyl heretofore encountered in such printing has been t e lack of a good means of main-'- mining the register'during the print-in Each color-printed requiresa difierent.impression to be given'to the fabric, and if the register is not perfect the colors will be printed in thefwrong places, and the effect of the picture, design, or printwill be lost and the workispoiled.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent lhe process of imprinting 'colors upon textile fabrice, by applying thereto-a paper back coated with dried paste dampened j ust before the fabric is attached; then imprinting it, and again dampening and detaching the fabric from the paper, all as described.
